Let's divide 330012 by 25
The aim is to understand the frequency of 25 in 330012.

On to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 25

Moving on to step 2:
When dividing 33 by 25, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 25 from 33 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 25

Moving on to step 3:
The number 25 fits into 80 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 75 from 80 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 25

Moving on to step 4:
When dividing 50 by 25, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we take 50 away from 50, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 25

Step 5:
25 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1320.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 25

Going ahead to step 6:
12 divided by 25 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 13200.0
If we subtract 0 from 12, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 25 fits into 120 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 13200.4
Deduct 100 from 120 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
25 goes into 200 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 13200.48
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13200.48
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13200.48
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 13200.48 with a remainder of 0.0.
